Loads of teachers. Lots like to teach outside their local area as it reduces the chances of bumping into kids at the weekend but also roads enable opportunities. My mother-in-law, now retired, used to teach miles away because that was where the head of department opportunity existed and the M25 enabled the journey. Build roads, create demand, create dependency. Of course it doesn't have to be like that but adjustments take decades both ways.
FFS. How many kids/teachers really can't get to school by foot, bike or public transport?
